Be itknown that I, ARTHUR ,B Goonsrnnn,

a citizen of the'United States, residing in Roseville, in'the State ofNew J ersey, have invent-m and useful Improvements in' Valve-Gear forInternal-Combustion Engines, i

ed certain new &c., of, which'the following, is a specification,reference being hadto theaccompany-v ing'drawings,iormingaparthereofi 5This invention relates generally to I inter rial-combustion engines thetypeof that shown ini ap licationfor Letters.Patent of the Unitedconstruction of the valves of such engin the-engine shown- 111 saidapplication the fuel-oil is admitted to a chamber "abovethe'i'nlet-valve, to which is also admitted the air under pressure, sothat vide'd for the 'pur ose the oil is: carried nto the "combustioncamber by the in'rushing air. Obviously'it is im oss ible in such a con-.struction to vary the a mission of the fuel-oil v with respect to theadmission bf the air.

a same time provisionis made for the-complete shutting off of both ofcombustion.

Another object isi t'c provide for a more thorou h atomization'of theoil as'it is admit-- directed upon the igniter, and thereted an fore fora better mirgcture of the oil and'theair, while "the oil,inevertheless,does not. lose I its physicalidentity until combustion begins. Bothparts of the improved valve are hper ated together by the valve-openingmeans, while that part which controls the admission of oil is clapableof operationindependently of the otherlpart'to provide fortheindependent regulation oftheadrnission of ,oiL. a

The means 'u'st described for operating the valve 712' are te same as those'shownin said application, Serial No. 202,720 but anyother suit-. able means maybe employed so far as concerns the presentinvention.-

the time-oi? the lifting will in general be determined by the action ofthe pump or the valve which regulates the supply of oil. The exactinstant of opening may, however, be regulated, as by the substitution ofa different sprin 0 or by the variation of its tension, as by a justingthe collar or the cap between which it is confined. In this manner thevalve 0 may be arran ed to open in advance of the lifting of the va vek. or at the same instant or later. It will be evident that when thevalve is lifted from its seat the oil will be distributed radiall in athin film upon the valve-seat and will. e instantly taken up by theinrushing air, which is also distributed in a conical sheet and alsocompletely atomized and mixed with the air, so that immediately uponcontact with the vaporizer and igniter M it will be thoroughlyvaporized.-

The valveseat, as will be noted, actsas a baffle-plate against which theoil is discharged, and the relation of the oil to the aircurrent is suchthat the atomization of the oil is-facilitated, while at the same timethe physical-condition of the oil is unchanged un' til vaporization andcombustion take place. Moreover, through the regulation of the instantof discharge of the oil, as already described, the character of themixture can be Varied as may be required under the particular conditionsof operation. It willbe understood, of course, that various changes inthe form and construction of' parts may be made without departing fromthe spirit of the invent-ion, and it is not intended to limit theinvention to the precise construction and arrangement shown anddescribed herein.
